Noise Control Materials

 

Typical Applications:

 

We carry extensive stocks of noise control materials which we can supply in sheet or roll form. Our material range covers a wide variety of specifications and we would be confident of being able to meet your particular requirements. A first class selection of adhesives and self-adhesives is available which have been formulated to operate under the most demanding conditions.

 

Our material range can be applied to provide a solution for both original equipment and in-plant noise problems. In order to clarify your requirements and identify the most appropriate material types to resolve your particular noise problem, we would be pleased to assist you in carrying out the necessary technical evaluation. As regards the final selection of materials, it should be noted that noise control materials are categorised into three distinctly different types as follows:

 

Sound Absorption

These materials which are mainly porous in order to dissipate the sound energy, are normally applied to surfaces to eliminate sound reflection and reduce reverberant noise build-up within an enclosed space. They are, for example, applied to the internal surfaces of equipment casings and noise enclosures for this purpose.

 

Sound Insulation

These materials, which form a sound barrier, are applied to attenuate the level of sound being transmitted through a panel, duct, wall or partition. It is their mass effect which provides the noise reduction and this can in many cases be further increased by the lamination to the material of a spacing layer, often a sound absorption material.


Vibration Damping

These materials are applied to reduce the vibration in panels, typically machinery casings, where it is the vibrating panel that is producing the noise. By damping the vibration in the panel the noise is thereby reduced at source. These materials also provide a level of sound attenuation, particularly at higher frequencies, and therefore when combined with a sound absorption material, the resulting composite noise control material is most effective for, as an example, the internal lining of sheet metal enclosures.
